ECHO ™ - The software package for simulation of hydraulic well listening (PC IGPS "ECHO") is designed for the rapid construction of a field-geological model of oil fields being developed.

A toolkit for systematic processing of geological and field observations of the operation of each well of the existing reservoir in the present and past tense mode in order to obtain additional data on the geological features of the structure of the developed field and information support in the management of oil production.


The existing options for adjusting the permanent geological-filtration model of an oil field are limited due to the following reasons:

  • lack of systematic updating of geological data and hydrodynamic research data;
  • chronic lack of information used for modeling;
  • economic factor limiting research costs primarily in long-developed and small-sized deposits, etc.

Therefore, there is a need to create a model of the oil recovery process, free from the above disadvantages

Conceptual framework

The geological and field model of the field, built using ECHO ™ , is based on one of the basic principles in the creation and management of a selection and injection system in oil production, which ensures the implementation of the phenomenon of interference (interaction) of wells.

Data used

The minimum information at which ECHO ™ performance is achieved includes: wellhead measurements of oil and water production and injection agent working volumes. The reliability of the results increases with the use of other borehole data, with less systematic measurements (reservoir pressure, static and dynamic levels, etc.). Such data are abundantly available in the fields, and most importantly, are systematically recorded by existing production accounting services. Thus, the solution of the main problems is ensured by easily accessible and abundant wellhead information (recorded in the Ministry of Economic Development, chess, operational cards). Therefore, all restrictions on the volume of work are removed and the goal of large-scale area studies of the oil recovery process is achieved. The accumulated experience working with the system shows that the solution of many urgent tasks of analysis and management of the development process would be impossible without its use.

Tasks and methods for solving them

To solve the basic problem (assessment of well interaction), the ECHO ™ software package makes extensive use of time series data processing algorithms modified to take into account the specifics of the profiles of monthly well operation data. The primary data goes through a filtering system (suppression of harmful noise).
To interpret the results of downhole information processing, proprietary algorithms and methods are used.
The basic task for realizing the potential of ECHO ™ is to evaluate the interaction of wells in real time and past tense. After solving the basic problem, you can proceed to the applied tasks.

Geological tasks:

  • Identification of non-conductive elements in the drained volume of the reservoir (including tectonic screens, lithological boundaries, clay lenses, etc.);
  • Assessment of the shielding properties of non-conductive elements (determination of the location of hydrodynamic "windows" and insulating sections);
  • Data pre-interpretation of the results of tracer studies (if they were conducted).

Tasks for information support of oil production:

  • Monitoring the interaction of production and injection wells and targeted recommendation for the regulation of production and injection in each well of the operating stock;
  • Mapping the process of forming channels of low filtration resistance at different sections of history;
  • Diagnostics of the location of man-made pillars of oil;
  • Comprehensive assessment of the technical effectiveness of geological and technical measures for groups of hydrodynamically connected wells.

The ECHO ™ software package proved to be excellent in working on a large number of projects in the Khanty-Mansi Autonomous Okrug, Western Siberia, Komi and Bashkiria. We have successfully completed a number of foreign projects on the shelf of India and Vietnam. According to the results of the first approbations of the PC IGPS “ECHO”, two copyright certificates were obtained:

  1. “A method for identifying non-conductive elements of an oil reservoir during its operation” (RF Patent No. 2229020);
  2. "Method for the study of oil reservoirs" (RF Patent No. 2298647)
  3. "A method for determining the filtration characteristics of a drained formation volume" (RF Patent No. 2382194)
